Answer:
#1- linear
#2- linear
#3- linear
#4- nonlinear
Step-by-step explanation:
A system of nonlinear equations is a system of two or more equations in two or more variables containing at least one equation that is not linear. A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A non linear looks like a u shape when graphed and a linear equation looks like a diagonal or straight line when graphed.

I believe the perimeter is 232. Since it's a regular polygon that means all the sides are equal so you take the two expressions on the sides of the polygon and set them equal to each other. Now you know that x=22 so you take that value and substitute it into one of the expressions to get the side length (x+7➡️22+7=29) now we know that each side length is 29. Since there are 8 sides you multiply 29 by 8 and get 232. Hope this helped!
A. Let the Initial Interest rate = x
It is given that each month Interest rate decreases by 1/4 point. Let total change of rate over the last six month= y
y = 6 x -x/4
y = -1.5x
B. Total Change
= (-1.5x-x)/(6-1)
= -2.5x/5
= -0.5x
= -5x/10
= -x/2
